UNITED STATES PATENT (OFFICE.-

FREDERICK W. WAKEFIELD, 0F VERMILLION, OHIO, ASSIGNOR TO FIELD BRASSCOMPANY, OF VERMILLION, OHIO, A CORPORATION OF OHIO.

To all whom it may concern:

.Be it knownthat I, FREDERICK W. WAKE- FIELD, a citizen of the UnitedStates and a resident of Vermillion, county of Erie, and State of Ohio,haveinvented a new and useful Improvement in Lighting-Fixtures, of whichthe following is a specification, the principle of the invention beingherein explained and the best mode in which I have contemplated applyingthat principle, so as to distinguish it from other inventions.

The subject of the present invention is mechanism for use in supportingthe bowls of stone or other translucent material which are now in suchgeneral use in connection with semi-direct lighting systems in which thegreater, part of the light is reflected from the bowl against theceiling, while a small part is transmitted through the trans: lucentmaterial of the bowl. These bowls are ordinarily of considerableweightand have to be firmly supported, and as they vary in size, even whennominally rated at the same diameter, it is necessary to have meanswhich can be adjusted slightly to correspond to the variations in sizeof the bowls and the means must have firm attachment to' the bowlitself.

The present improvements provide a secure means for supporting the bowland are at the same time simple and relatively inexpensive. Y

To the accomplishment of the foregoing and related ends, said invention,then, consists of the means hereinafter fully described and particularlypointed out in the claims.

The annexed drawings and the following description set forth in detailcertain mechanism embodying'the invention, such disclosedmeansconstituting, however, but one of various mechanical formsin whichthe principle, of theinvention may be used.

In said annexed drawings Figure 1 is a view in perspective of the bowlsupported by an external ring; F ig. 2 is a section'on the line 2-2 inFig. 1; Fig. 3 is a view in perspectiveof one of'the hooks mounted uponthe ring; Fig. 4:is a similar view of a portion of the ring; Fig. 5 is aperspective view of adjacent ends of the rin g; F ig. 6 isa view inperspective of a similar. type of; b owl,,but supported from within;Fig.

7 is a view similar to Fig. 2 but taken on V the line 7 7 in Fig.6,;Fig. 8 is a horizon-. tal sectional view" of thering used in. FigsQ 6and 7; Fig. 9 is a transverse section of the ring shown in Fig. 8; Fig.10 is. a side elevation of the ring shown in Fig. .8; F 1g.

11 is a perspective view of one of the hooks used in this type of ring.I

Referring now to Fig. 1, there is shown a bowl 1 of suitable material,formed with; a circumferentially extending curved flange 2 at its upperedge. My improvements in-v elude-a concave ring 5 extending completely.

around the bowl and cooperating with the circumferential flange 2 tosupport the bowl.

'In the form illustrated in Figs. 1 to 3, this ring 3 is split and uponone of the ends is attached a bracket 4 provided with a:

threaded opening 5. On'the other endof the ring 3 there is a secondbracket or hook 6 in which there .is mounted a screw 7 adapted toregister with :and enter the threaded opening 5 in the bracket 4:, thusdrawing the ends of the ring together and clamping the same securelyupon the flange 2 of the bowl. It is customary with such bowls toprovide three or; more supports the inner side of the curved brackethooks.

1.0. To engage these hooks over the ring, the lug 9 is first? insertedin the recess or notch 8 and the hook is thenswung around into contactwith the outside of the ring,

thus bringing" a second lug 11 adjacent to the upper edge of the ring.'The lugs 9 which are offflexible material, such as soft brass, are thenclamped inwardly Ias illus trated dotted lines: in Fig. 2, thuspreventing disengagement of the hook from. i

the ring and maintaining; the same in the desiredfpositioncircumferentially to the ring. [The bracket hooks 10. are provided at'their'upper ends with curved portions.

12 adapted tobe engaged by the supporting.

chain :13 asillu'strated in. Fig. 1, and thereare also provided inwardlydirecte d,. downwardly sloping lamp sockets 14." It is'cu'stomaryinsuchbo wls to have three or four;

lamp bulbs-which lie at anglesto radial bowl of this type is provided atits upper edge with an inwardly curved flange 15 within which there ismounted a split ring 16 of semicircular cross section as illustrated,this ring fitting snugly against the inner side of the flange 15, andbeing securely clamped to the same in the followingmanner. Referring nowto Figs. 8, 9 and 10, the two ends of the ring 16 overlap to someextent, the end 17 being compressed to fit snugly and slidably withinthe other end 18'. Attached to the end 18 at right angles thereto, is ascrew'or stud 19 uponwhich is adjustab-ly mounted a set screw 20. Theend 11 has movement past this set screw and stud, by reason. of a slot21 therethrough in which the stud 19 lies. In order to insert a ring ofthis typein such a bowl, the set screw is loosened and the ring iscompressed circumferentially until or a sufliciently small :size topermit of its introduction within the flange 15 of the bowl. The ring isthen expanded until it fits the flange 15 snugly, when the set screw isadjusted to maintain it in that po- F sition, in which it is in secureengagement in the bowl.

In Fig. 7 the method of attachment of the supporting hooks 9.2 is shown,these hooks being provided with curved bowls23 adapted to fit snuglywithin the ring16, where they are held at suitable intervals around thesame by means of screws 245 whose holding action may be augmented by theuse of solder if desired, the appearance of the ring in. this case notbeing important as no part of the ring can be seen by a person in theroom when the bowl is hung from the ceiling.

.These hooks 22 are provided with curved portions or hooks proper 25, towhich may be attached the supporting rods26, and are provided, as arethe hooks shown in Figs. 1 to 5, with inwardly directed and downs wardlyextending bulb sockets 27.

The two types of supporting rings here shown for bowls of this generaltype, are notonly extremely inexpensive to manufac ture but are neat inappearance and provide-a very secure engagement of the bowl, andanengag'ement which cannot be secured by any other means now in useunless the means are attached to the bowls before the same are suppliedto the workmen in the rooms where they are to be located. Onthe otherhand, the presentmeans can be securely attached to any bowl by anyworkman and need not be assembled before the bowls are delivered to theplace where they will be used} Other modes ofapplying the principle of:

ing claims or the equivalent-of such stated means be employed.

I therefore particularly point out and dis-' tinctly claim as myinvention 1. The combination: with a bowl havinga circumferential flangealong its 7 upperedge, of a split rlng formed to snugly en-:

of. a split ring formed to snuglyengage.

against such flange, and a plurality of hooks attached to said ring andlying within the periphery of said bowl, one of said hooks beingprovided with an integral extension having a threaded OpBIfiHgthQIGiIi;formed. to recelve a light bulb and maintain; the same at a slight angleto the hor zontal;

3. The combination with a bowl havinga circumferentially disposed,laterally project ing flange of convex exterior aboutits edge, of asplit ring of convex lnterior adapted to snugly contact the outside ofsuch flange,

and having alined openings at its ends, and '1 a member adjustablyengagingin such openings to securely engage saidring' against;

such flange.

4. The combinationwith a bowl having a circumferentially disposed,laterally pro jecting flange of convex exterior about its edge, of asplit ring of convex interior adapted to snugly contact the outside ofsuch flange, and having alined openings at its. ends, a memberadjustably engaging in. such openings to securely engage said ring,
